Red Mars - Red Mars opens with a tragic murder, an event that becomes the focal point for the surviving characters and the turning point in a long intrigue that pits idealistic Mars colonists against a desperately overpopulated Earth, radical political groups of all stripes against each other, and the interests of transnational corporations against the dreams of the pioneers.

This is a vast book: a chronicle of the exploration of Mars with some of the most engaging, vivid, and human characters in recent science fiction. Robinson fantasizes brilliantly about the science of terraforming a hostile world, analyzes the socio-economic forces that propel and attempt to control real interplanetary colonization, and imagines the diverse reactions that humanity would have to the dead, red planet.

Red Mars is so magnificent a story, you will want to move on to Blue Mars and Green Mars. But this first, most beautiful book is definitely the best of the three. Readers new to Robinson may want to follow up with some other books that take place in the colonized solar system of the future: either his earlier (less polished but more carefree) The Memory of Whiteness and Icehenge, or 1998's Antarctica. - Amazon.com

Blue Mars - While Mars flourishes, Earth is threatened by overpopulation and ecological disaster. People look to Mars as a refuge, initiating a possible interplanetary conflict, as well as igniting a political struggle between the Reds, who wish to preserve the planet in its desert state, and the Green "terraformers".
